I sold my apartment in Israel and made a profit. However, I needed to buy a house in South Bend with the money and even with all the money I needed in addition to take a mortgage. Do I need to give ma’aser on the profit that I earned on my apartment in Israel?
Ultimately, you will need to give ma’aser. However, you do not need to give it right now. If you have extra money you should give the ma’aser now but if you don’t as would seem to be the case (bearing in mind that you took out a mortgage) you can write down the ma’aser as a loan and when you indeed have extra money you can then give the ma’aser. The reason for this is that one need not borrow money in order to pay ma’aser.
